I've had a CNC mill (and mach3) for a while but not had the time to play with them - now I have the time but the first steps seem rather daunting. As a first CNC project I want to machine an "S" shape out of a flat plate, preferably with beveled edges. It would be good to be able to do simple engraving on the top.
Is there a good (free, ideally) CAD package to do the drawing in? Once I've got a drawing, how do I generate the G-code for mach3.
(Apologies for the very basic questions but we all have to start somewhere and I would be very grateful for any guidance)
